The only things left after the engine are transmission and transfer case, fingers crossed they'll be good for a bit!

Truck is going back in to the shop this week, hopefully the engine is out by next weekend.
I've been referred to a machine shop in Calgary, the guy who owns it is a 12 valve wizard apparently. He's been working on them and overhauling them for over 20 years. Hopefully in a months time the truck will have a brand new heart, and be better than it was when the engine was brand new.
I'll post updates as I get them!

Engine is out, I dropped it off at the machine shop this morning.
Guy seemed quite knowledgeable about all things B-model Cummins.
We won't know what's wrong inside until it's pulled apart but just by looking at it, he noticed a few things wrong with it for a pickup application. He's thinking a combination of not enough things in some areas and not the proper things in others were changed when this engine was converted from industrial use to a pickup use engine.
If there's a silver lining to the engine problems happening, at least it's going to be new when it's done and it'll be put back together properly for what it's going to be doing. There might be an extra upgrade or two going in to it while we're this deep too.

I got an update from the engine shop yesterday. The #6 piston had failed and it looked like it was stuck in the cylinder for a brief moment, most likely when the engine died and the clutch was smoked, it was definitely the cause of the ticking.
On top of that, it looks like the internals of the engine got quite hot at some point in its life. 3 connecting rods got hot enough that they started to blue. By the looks of the bearings and the bottom end it looked like someone did a part way overhaul and went in through the oil pan and did some work to the bottom end without pulling pistons out.
Nothing that they have found so far can't be fixed, they're starting to clean parts today and come up with a list of what's needed.

Good to hear Will....You made the right choice and now you have some answers.....

It's always good feeling when you know you made the right decision to pull it out. It'll be fresh and correct when you get it back for many miles of smiles.

Hey Will....did you get a autopsy report on your engine ???

Nothing more yet than what I posted a couple weeks ago about the #6 piston and the bluing of 3 of the rods.
Engine will hopefully be finished by the weekend. It'll have proper sized injectors in it, a new turbo with the right size exhaust turbine so it's going to spool quicker, 3000 rpm governor springs, heavy duty head studs and a few other mods to whip out in to shape.
The engine guy could tell from what he saw and took apart that it would have been quite gutless but he assures me it'll be producing a lot more power now.
Hopefully the weather stays decent so I can get a few miles on it once it's back in the truck.

I picked the engine up today, one step closer to getting back on the road. I can't wait to drive it and see how different it feels.
Pictures are of the #6 piston, that's what was causing the ticking.

Thats a ugly piston...I have heard they can lean out on the end cyl's due to the inlet on the intake.That is why I am making a dual inlet intake for mine..My friend put a dual inlet intake (Banks) on his Cummins Dodge truck and said it made a huge difference....The new engine Will should last you your life time..Is a exhaust brake in the plans..I have a Pak-brake exhaust brake..Holy Fu*K does it haul that truck down in 3rd gear..Need to get my truck fired up again..Friken divorces can sure screw a man up....

We did put an exhaust brake on it last winter when we did the exhaust.
I can't remember what make it is but the performance of it isn't that remarkable. With all the changes that have been made to the engine im hoping I'll notice an improvement with it as well.

A piston with skirt damage like that should have made a little more noise than a click.

Not Grizzly but it is my thread so....Shifter knobs for my 36 Diamond T 212BD..I put a Brownie 3spd box in it when I rebuilt the truck..Yes I paid dearly for the knob with the brass inlay..
